The game largely deviated from normal ''Tetris'' gameplay, yet it received high ratings from critics.
Released exclusively on the Nintendo 64, this game is almost entirely different from the standard ''Tetris'' formula. It started out as an Atari Jaguar game titled ''Phear'', on display at CES '95. Nintendo bought the rights to the game from its developer, and released it two years later as Tetrisphere.
 
== Gameplay ==
Instead of starting with an empty playfield and placing pieces, each level consists of a core surrounded by layers of pieces. Although the game's playfield appears to be a sphere (due to only a circular portion of it being visible at any time), it is actually a 32x32 torus, which ensures that no matter which direction the player moves around the field, the pieces remain in the same orientation.
 
The objective in most game modes is to clear pieces from each layer of the game field, exposing enough of the core to free the robot trapped inside. This is accomplished by dropping pieces to form a group of three or more of the same type, to clear those and any other identical pieces touching the first group. The cursor shows where the current piece will be placed, and this cursor can be moved around with the digital control pad. The cursor will turn bright if placing the piece will start a reaction. Pieces are placed by pressing the A button, and it is possible to slide pieces of the same type as the current piece by moving the cursor over them and holding B. When holding B over a movable piece, the control pad can be used to move the piece. A piece preview on the lower left corner of the screen shows the piece currently held, as well as the next two pieces.
 
The player has three lives to complete each level. Placing a piece where it will not start a reaction takes away one life. There is also a multi-colored timer, which ticks down when the player is not clearing pieces. If the blue timer runs out, the yellow timer will start ticking, and the camera will slowly zoom towards the field. If it hits the field, the player loses a life.
 
For each game mode except Puzzle, the player can select one of several characters to play as. Each character has two statistics, both of which influence the auto-repeat rate of cursor movement under different conditions. Speed determines how fast the cursor will move normally, and Power determines how fast it will move when sliding a piece.
 
== Pieces ==
There are six types of pieces in total, and any gaps between pieces on the field are initially filled by 1x1 crystal pieces. Usually, levels don't use all six types of pieces at the same time. Crystal pieces can be broken by sliding other pieces into them, or clearing other pieces next to them. Blue O pieces must be placed at 90-degree angles in order to be cleared together. This also applies to the green I pieces, and the yellow horizontal I pieces, both of which are only three blocks long. Red T pieces, cyan Z pieces, and small pink L pieces need only touch each other at any edge to be cleared together. Two or more pieces on adjacent layers must be exactly on top of each other to be cleared together. Sometimes the player will receive a wild card piece. This piece can be dropped as any type of piece, and can be used to slide any piece on the field.
 
== Power Pieces and Special Combos ==
Every time pieces are cleared from the field, certain remaining pieces will be transformed into glowing Power Pieces. These can slide up over other pieces, one layer at a time. Also, clearing a Power Piece replenishes the timer greatly, and reactions started with a Power Piece take longer to clear than normal reactions, which makes it easier to start another reaction while the first reaction is still clearing. Specifically, every time a set of pieces is cleared, one Power Piece is obtained for every regular piece that was cleared. A Power Piece can be obtained without having to clear pieces by moving the cursor over a like-shaped formation of crystal pieces, and pressing B.
 
Two types of special combos can increase the player's X count, which acts as a multiplier to points earned from clearing pieces. A Gravity Combo can be executed by causing one piece to fall and form a group, by either clearing or sliding a piece that is holding it up. A Fuse Combo can be executed by starting a reaction with a Power Piece, then grabbing one of the flashing pieces with B before it gets cleared, and sliding it to another group.
 
== Weapons ==
In general, for every 20 pieces the player clears, a weapon is received. If the player already has a weapon, it is upgraded to the next level. The weapons can be used to clear pieces and reach the core quickly. Sometimes a 1x1 weapon crystal can be found on the game field, and it will give the player a weapon or upgrade their current one if broken open. The Firework will clear a small area on the top layer. The Dynamite splits into five to cover a wider area than the Firework. The Magnet rapidly zaps away pieces over the spot that is targeted. The Molecule will remove the entire top layer of pieces from the field. The Atom Bomb creates a deeper explosion that reaches through multiple layers. The Laser acts like a much more powerful version of the Magnet.
 
== Game Modes ==
Rescue is the basic game mode, in which the player clears levels by exposing the core of each one to free the robots trapped inside them.
 
Hide and Seek is similar to Rescue, but each stage can have one of many special objectives assigned to it. For instance, the player might be required to reach the core of the game field without damaging a crystal tower placed in a certain location.
 
In Time Trial mode, the player goes through stages nonstop, earning points as fast as possible until the clock hits zero.
 
In Puzzle mode, each level has a configuration of pieces, and the player must clear them all, using a limited number of slides and drops. There is no time limit, pieces cannot be dropped where they will not clear a group, and every piece is a wild card piece. The camera can also be zoomed in and out to take a carefully look at the layout of pieces.
 
In Vs. Mode, the player can compete against either another player or the CPU, trying to reach the core of their gamefield first.

Released exclusively on the Nintendo 64, this game is almost entirely different from the standard Tetris formula. It started out as an Atari Jaguar game titled Phear, on display at CES '95. Nintendo bought the rights to the game from its developer, and released it two years later as Tetrisphere.

Gameplay

Instead of starting with an empty playfield and placing pieces, each level consists of a core surrounded by layers of pieces. Although the game's playfield appears to be a sphere (due to only a circular portion of it being visible at any time), it is actually a 32x32 torus, which ensures that no matter which direction the player moves around the field, the pieces remain in the same orientation.

The objective in most game modes is to clear pieces from each layer of the game field, exposing enough of the core to free the robot trapped inside. This is accomplished by dropping pieces to form a group of three or more of the same type, to clear those and any other identical pieces touching the first group. The cursor shows where the current piece will be placed, and this cursor can be moved around with the digital control pad. The cursor will turn bright if placing the piece will start a reaction. Pieces are placed by pressing the A button, and it is possible to slide pieces of the same type as the current piece by moving the cursor over them and holding B. When holding B over a movable piece, the control pad can be used to move the piece. A piece preview on the lower left corner of the screen shows the piece currently held, as well as the next two pieces.

The player has three lives to complete each level. Placing a piece where it will not start a reaction takes away one life. There is also a multi-colored timer, which ticks down when the player is not clearing pieces. If the blue timer runs out, the yellow timer will start ticking, and the camera will slowly zoom towards the field. If it hits the field, the player loses a life.

For each game mode except Puzzle, the player can select one of several characters to play as. Each character has two statistics, both of which influence the auto-repeat rate of cursor movement under different conditions. Speed determines how fast the cursor will move normally, and Power determines how fast it will move when sliding a piece.

Pieces

There are six types of pieces in total, and any gaps between pieces on the field are initially filled by 1x1 crystal pieces. Usually, levels don't use all six types of pieces at the same time. Crystal pieces can be broken by sliding other pieces into them, or clearing other pieces next to them. Blue O pieces must be placed at 90-degree angles in order to be cleared together. This also applies to the green I pieces, and the yellow horizontal I pieces, both of which are only three blocks long. Red T pieces, cyan Z pieces, and small pink L pieces need only touch each other at any edge to be cleared together. Two or more pieces on adjacent layers must be exactly on top of each other to be cleared together. Sometimes the player will receive a wild card piece. This piece can be dropped as any type of piece, and can be used to slide any piece on the field.

Power Pieces and Special Combos

Every time pieces are cleared from the field, certain remaining pieces will be transformed into glowing Power Pieces. These can slide up over other pieces, one layer at a time. Also, clearing a Power Piece replenishes the timer greatly, and reactions started with a Power Piece take longer to clear than normal reactions, which makes it easier to start another reaction while the first reaction is still clearing. Specifically, every time a set of pieces is cleared, one Power Piece is obtained for every regular piece that was cleared. A Power Piece can be obtained without having to clear pieces by moving the cursor over a like-shaped formation of crystal pieces, and pressing B.

Two types of special combos can increase the player's X count, which acts as a multiplier to points earned from clearing pieces. A Gravity Combo can be executed by causing one piece to fall and form a group, by either clearing or sliding a piece that is holding it up. A Fuse Combo can be executed by starting a reaction with a Power Piece, then grabbing one of the flashing pieces with B before it gets cleared, and sliding it to another group.

Weapons

In general, for every 20 pieces the player clears, a weapon is received. If the player already has a weapon, it is upgraded to the next level. The weapons can be used to clear pieces and reach the core quickly. Sometimes a 1x1 weapon crystal can be found on the game field, and it will give the player a weapon or upgrade their current one if broken open. The Firework will clear a small area on the top layer. The Dynamite splits into five to cover a wider area than the Firework. The Magnet rapidly zaps away pieces over the spot that is targeted. The Molecule will remove the entire top layer of pieces from the field. The Atom Bomb creates a deeper explosion that reaches through multiple layers. The Laser acts like a much more powerful version of the Magnet.

Game Modes

Rescue is the basic game mode, in which the player clears levels by exposing the core of each one to free the robots trapped inside them.

Hide and Seek is similar to Rescue, but each stage can have one of many special objectives assigned to it. For instance, the player might be required to reach the core of the game field without damaging a crystal tower placed in a certain location.

In Time Trial mode, the player goes through stages nonstop, earning points as fast as possible until the clock hits zero.

In Puzzle mode, each level has a configuration of pieces, and the player must clear them all, using a limited number of slides and drops. There is no time limit, pieces cannot be dropped where they will not clear a group, and every piece is a wild card piece. The camera can also be zoomed in and out to take a carefully look at the layout of pieces.

In Vs. Mode, the player can compete against either another player or the CPU, trying to reach the core of their gamefield first. When enough pieces are cleared, dark pieces will be sent to the opponent's field. These cannot be cleared directly, but must be cleared by adjacent pieces. Each round ends when one player exposes enough sections of their core, or loses all three of their lives.
